REINFORCEMENT FOR TIRE-CASINGS.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed January 2, 1919. Serial No. 269,189.

To all whom it may concern:

Be it known that I, TOMMY JOSEPH CoN- VERSE, a citizen of the UnitedStates, residing at Bellingham, in the county of Whatcom and State ofWashington, have invented a new and useful Reinforcement forTire-Casings, of which the following is a specification.

It is the object of this invention to provide a novel reinforcementadapted to be applied to rim-cut tire casings.

Within the scope of what is claimed, a mechanic may make changes withoutdeparting from the spirit of the invention.

In the drawings Figure 1 shows a side elevation, a portion of a tirecasing whereunto one form of the invention has been applied; Fig. 2 is across section of the structure shown in Fig. 1; Fig. 3 is a sideelevation showing a portion of a tire casing whereunto a modified formof the invention has been applied; and Fig. 4 is a cross section of thestructure shown in Fig. 3.

In carrying out the invention as shown in Figs. 1 and 2, the numeral 1designates a rim having a clencher flange 2. A tire casing 3 cooperateswith the rim 1 and includes a bead 4 coiiperating with the clencherflange 2 and defining a groove 40. The numeral 5 designates a plate,preferably made of metal. In its outer edge, the plate 5; is providedwith notches 6 and 7, the notch 6 being deeper than the notch 7. Thenotches 6 and 7 define terminal arms 8 and an intermediate arm 9. Allofthe arms 8 and 9 are of different lengths, the arms being of taperedconstruction, as clearly shown in Fig. 1. The outer ends of the terminalarms 8 are in alinement, whereas the outer end of the intermediate arm 9is set back somewhat from a line tangent to the outer ends of the arms8. The arms 8 and 9 terminate in bendable prongs 10 clenched in the tirecasing 3. In the inner edge of the plate 5, notches 11 and 12 areformed, these notches like the notches 6 and 7 being V-shaped. The notch11 is deeper than the notch 12. The notches 11 and 12 define terminalinner arms 14 and an intermediate terminal arm 15. Thenotches 11 and 12are of tapered alluded to have been designated by numerals previouslyused, with the suflix' a. In this form of the invention, the plate 5 hasbut a single hook 16, the plate being attached to the tire casing 3' bymeans. of rivets 17. The plates 5 are applied to'jthe tire casing 3 inspaced relation, circumferentially of the casing, and at any desireddistances apart, this observation holding true with respect to theplates 5 of Fig. 3. .Any desired sort of metal may be used in. themaking of the plates 5 and 5.

Owing to the specific form given to the plate 5, the same will possess-great strength with a minimum expenditure of material, and in thisconnection it is to be observed that the deeper notch 11 in the inneredge of the plate is disposed opposite, or approximately opposite, tothe shallower notch 7 in the outer edge of the plate, the deeper notch 6in the outer edge of the late being disposed approximately op os1te tothe shallower notch 12 in the inner edge of the plate. Since the arm 9is shorter than the arms 8, all of the clenching prongs 10 will notengage the tire casing 3 in the same line and, consequently, thepossibility of tearing the tire casing is reduced to a minimum.

Having thus described the invention, what is claimed is 1. Areinforcement for tire casings, comprising a plate provided in itsopposite edges with notches defining first and second arms, the firstarms terminating in clenching prongs and the second arms terminating inhooks, the notches in the respective edges of the late being ofdifferent lengths, whereby the 11st arms will be of different lengthsand whereby the second arms-will be of different lengths.

2. A reinforcement for tire casings comprising a plate provided initsopposite edges testimony that I claim the foregoing as i with notchesdefining first and second arms, my own, I have hereto aflixed myslgnature the first arms terminating in clenching in the presence of twowitnesses.

prongs, and the second ianns terminating in TOMMY JOSEPH CONVERSE 5hooks, the outer end :of one of the first arms Witnesses:

being set inwardly: from the outer ends of WILLIAM McCUsn,
